Egyptian security forces killed six suspected militants in a raid on a house on the outskirts of Cairo, an interior ministry statement said.
The men were planning to attack “vital installations and Christian places of worship and the armed forces and police during the (Muslim) Eid al-Adha celebrations,” the ministry said.
The ministry published photos of bloodied bodies with faces concealed and assault rifles and shotguns beside them.
The raid in the 6th October suburb came days after an attempted attack on a church near Cairo. Security forces arrested seven people suspected of involvement in Saturday’s foiled bombing, the latest attack on Egypt’s Christian minority.
Separately, Egyptian forces killed 12 suspected militants in raids in North Sinai, state media reported.
President Abdel Fattah al-Sisi promised to defeat Islamist militants, who killed hundreds of civilians and security force members in the Sinai Peninsula in recent years. Some attacks targeted the Egyptian mainland.
The Eid festival takes place next week. Egypt usually tightens security measures before national holidays, around which attacks have happened since 2011.
